Also: unless you're genuinely curing cancer or flying food to starving African villages or something, 95% of software companies are pretty damn useless and any impact a SWE imagines is basically just a mental fantasy that helps one keep working. No one is genuinely happier because another API is created or some rich person has a better way of managing which products he's selling to other rich people. It's all basically useless and just a way to make money.
